The LOCAL MODE setpoint places the relay in local mode. The relay is in remote mode if not forced into local mode by this
setpoint. The RESET setpoint resets the last trip indicator and latched relays. With the 760, it also resets the autoreclose
lockout. The COLD LOAD PICKUP setpoint initiates the Cold Load Pickup blocking feature. The SETPOINT GROUP 2 through
SETPOINT GROUP 4 setpoints signal the relay to make Group 2, 3, or 4 the active setpoint group.
The
REMOTE OPEN and REMOTE CLOSE setpoints initiate a breaker opening via the Trip Relay and a breaker closure via the
Close Relay, respectively. These setpoints are operational only when the relay is in remote mode (see above).
5.4.5 USER INPUTS
PATH: SETPOINTS ÖØ S3 LOGIC INPUTS ÖØ USER INPUTS Ö USER INPUT A(T)
There are twenty (20) general purpose user input functions (User Inputs A through T) that generate outputs in response to
an asserted logic input. These functions can be used to: initiate a trip; initiate a trip and a reclosure (760 only); log a contact
operation in the event recorder; convert an external contact into a self-resetting, latched or pulsed contact.; convert an
external contact into a Form-C contact; and provide a contact multiplier for an external contact by operating multiple relays.
The setpoints for User Input A are shown above; setpoints for User Inputs B through T are identical.
